PCB afterburner max power

[LegionPleingaz]

Hello
Is it possible to note the maximum power for the hotend? depending on the width and thickness of the track (internal or external). example: for a 70W cartridge under 24 volts I need 2.9A -> 3A.
For an internal track I therefore need a width of 2.8mm with a thickness of 35um or 1.4mm with a thickness of 70um.
I know it also depends on the manufacturer of the PCB more than the design, but it seemed to me that was an important safety point.
